FIELD OF THE INVENTION

This invention provides nuclear hormone receptor binding compounds and uses thereof in treating a variety of diseases or conditions in a subject, including, inter-alia, prostate cancer and/or diseases or disorders of bone and muscle.

BACKGROUND OF THE INVENTION

The nuclear hormone receptor superfamily is one of the largest classes of transcription factors and is involved in abundant physiological processes. The 48 members of this family are divided into three classes with class 1 comprised of receptors for androgens (AR), estrogens (ER-α and ER-β), glucocorticoids (GR), progesterone (PR) and mineralocorticoids (MR). Class 2 contains receptors for retinoids, thyroids and vitamin D, while class 3 includes receptors for which ligands are yet to be identified (orphans). Nuclear hormone receptors have an N-terminal domain (NTD) whose function is less characterized, a DNA binding domain (DBD) which is responsible for the binding of receptor to DNA response elements, a hinge region that contains the nuclear localization signal and a ligand binding domain (LBD) to which ligands bind and activate or inhibit receptor action. In addition, there are two activation function domains, one in the NTD (AF-1) and the other in the LBD (AF-2). Due to the high amino acid sequence homology of the DBD, moderate homology and similar secondary and tertiary structural features of the LBD, and common chemical features of steroidal ligands, class I receptors are often capable of binding (i.e., cross reacting) with the ligands of other class I receptors. For example, early studies with AR and ER suggest that the orientation of the steroid in the LBD, with the steroid A-ring in contact with helix-3 and the D-ring in contact with helix-11 residues, is likely to be general for all the steroid hormone receptors.

The androgen receptor (“AR”) is a ligand-activated transcriptional regulatory protein that mediates induction of male sexual development and function through its activity with endogenous androgens. Androgens are generally known as the male sex hormones. The androgenic hormones are steroids which are produced in the body by the testes and the cortex of the adrenal gland or can be synthesized in the laboratory. Androgenic steroids play an important role in many physiologic processes, including the development and maintenance of male sexual characteristics such as muscle and bone mass, prostate growth, spermatogenesis, and the male hair pattern (Matsumoto, Endocrinol. Met. Clin. N. Am. 23:857-75 (1994)). The endogenous steroidal androgens include testosterone and dihydrotestosterone (“DHT”). Testosterone is the principal steroid secreted by the testes and is the primary circulating androgen found in the plasma of males. Testosterone is converted to DHT by the enzyme 5 alpha-reductase in many peripheral tissues. DHT is thus thought to serve as the intracellular mediator for most androgen actions (Zhou, et al., Molec. Endocrinol. 9:208-18 (1995)). Other steroidal androgens include esters of testosterone, such as the cypionate, propionate, phenylpropionate, cyclopentylpropionate, isocarporate, enanthate, and decanoate esters, and other synthetic androgens such as 7-Methyl-Nortestosterone (“MENT”) and its acetate ester (Sundaram et al., “7 Alpha-Methyl-Nortestosterone(MENT): The Optimal Androgen For Male Contraception,” Ann. Med., 25:199-205 (1993) (“Sundaram”). Because the AR is involved in male sexual development and function, the AR is a likely target for effecting male contraception or other forms of hormone replacement therapy.

The human progesterone receptor (PR) occurs as three different isoforms: PR-A, PR-B, and PR-C (Kastner et al., EMBO J 9:1603-1614, 1990; Wei et al., Mol Endo 10:1379-1387, 1996), of which PR-A and PR-B are the most abundant. However, the ratio of PR-A vs. PR-B isoforms is not constant among target tissues, and this can alter the cellular response, because the activity of each isoform can vary.

There are very few compounds that exhibit partial progestin activity under a wide variety of conditions. RU-486, the most commonly used antiprogestin, displays partial agonist activity only under selected conditions. Antiprogestin compounds with partial agonist activity are useful for treating various progestin-regulated diseases and conditions, however, the few known antiprogestins have only limited partial agonist activity, and there remains a need in the art for antiprogestins with broad-range partial agonist activity.

Worldwide population growth and social awareness of family planning have stimulated a great deal of research in contraception. Contraception is a difficult subject under any circumstance. It is fraught with cultural and social stigma, religious implications, and, most certainly, significant health concerns. This situation is only exacerbated when the subject focuses on male contraception. Despite the availability of suitable contraceptive devices, historically, society has looked to women to be responsible for contraceptive decisions and their consequences. Although concern over sexually transmitted diseases has made men more aware of the need to develop safe and responsible sexual habits, women still often bear the brunt of contraceptive choice. Women have a number of choices, from temporary mechanical devices such as sponges and diaphragms to temporary chemical devices such as spermicides. Women also have at their disposal more permanent options, such as physical devices including IUDs and cervical caps as well as more permanent chemical treatments such as birth control pills and subcutaneous implants. However, to date, the only options available for men include the use of condoms and vasectomy. Condom use, however is not favored by many men because of the reduced sexual sensitivity, the interruption in sexual spontaneity, and the significant possibility of pregnancy caused by breakage or misuse. Vasectomies are also not favored. If more convenient methods of birth control were available to men, particularly long-term methods which require no preparative activity immediately prior to a sexual act, such methods could significantly increase the likelihood that men would take more responsibility for contraception.

Administration of the male sex steroids (e.g., testosterone and its derivatives) has shown particular promise in this regard due to the combined gonadotropin-suppressing and androgen-substituting properties of these compounds (Steinberger et al., “Effect of Chronic Administration of Testosterone Enanthate on Sperm Production and Plasma Testosterone, Follicle Stimulating Hormone, and Luteinizing Hormone Levels: A Preliminary Evaluation of a Possible Male Contraceptive, Fertility and Sterility 28:1320-28 (1977)). Chronic administration of high doses of testosterone completely abolishes sperm production (azoospermia) or reduces it to a very low level (oligospermia). The degree of spermatogenic suppression necessary to produce infertility is not precisely known. However, a recent report by the World Health Organization showed that weekly intramuscular injections of testosterone enanthate result in azoospermia or severe oligospermia (i.e., less than 3 million sperm per ml) and infertility in 98% of men receiving therapy (World Health Organization Task Force on Methods And Regulation of Male Fertility, “Contraceptive Efficacy of Testosterone-Induced Azoospermia and Oligospermia in Normal Men,” Fertility and Sterility 65:821-29 (1996)).

A variety of testosterone esters have been developed which are more slowly absorbed after intramuscular injection and thus result in greater androgenic effect. Testosterone enanthate is the most widely used of these esters. While testosterone enanthate has been valuable in terms of establishing the feasibility of hormonal agents for male contraception, it has several drawbacks, including the need for weekly injections and the presence of supraphysiologic peak levels of testosterone immediately following intramuscular injection (Wu, “Effects of Testosterone Enanthate in Normal Men: Experience From a Multicenter Contraceptive Efficacy Study,” Fertility and Sterility 65:626-36 (1996)).

Bone mineral density (BMD) decreases with age in both males and females. Decreased amounts of bone mineral content (BMC) and BMD correlate with decreased bone strength and predispose patients to fracture.

Osteoporosis is a systemic skeletal disease, characterized by low bone mass and deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. In the U.S., the condition affects more than 25 million people and causes more than 1.3 million fractures each year, including 500,000 spine, 250,000 hip and 240,000 wrist fractures annually. Hip fractures are the most serious consequence of osteoporosis, with 5-20% of patients dying within one year, and over 50% of survivors being incapacitated. The elderly are at greatest risk of osteoporosis, and the problem is therefore predicted to increase significantly with the aging of the population. Worldwide fracture incidence is forecasted to increase three-fold over the next 60 years, and one study estimated that there will be 4.5 million hip fractures worldwide in 2050.

Women are at greater risk of osteoporosis than men. Women experience a sharp acceleration of bone loss during the five years following menopause. Other factors that increase the risk include smoking, alcohol abuse, a sedentary lifestyle and low calcium intake. However, osteoporosis also occurs frequently in males. It is well established that the bone mineral density of males decrease with age. Decreased amounts of bone mineral content and density correlates with decreased bone strength, and predisposes to fracture. The molecular mechanisms underlying the pleiotropic effects of sex-hormones in non-reproductive tissues are only beginning to be understood, but it is clear that physiologic concentrations of androgens and estrogens play an important role in maintaining bone homeostasis throughout the life-cycle. Consequently, when androgen or estrogen deprivation occurs there is a resultant increase in the rate of bone remodeling that tilts the balance of resorption and formation to the favor of resorption that contributes to the overall loss of bone mass. In males, the natural decline in sex-hormones at maturity (direct decline in androgens as well as lower levels of estrogens derived from peripheral aromatization of androgens) is associated with the frailty of bones. This effect is also observed in males who have been castrated.

Muscle wasting refers to the progressive loss of muscle mass and/or to the progressive weakening and degeneration of muscles, including the skeletal or voluntary muscles, which control movement, cardiac muscles, which control the heart (cardiomyopathics), and smooth muscles. Chronic muscle wasting is a chronic condition (i.e. persisting over a long period of time) characterized by progressive loss of muscle mass, weakening and degeneration of muscle.

The loss of muscle mass that occurs during muscle wasting can be characterized by muscle protein degradation by catabolism. Protein catabolism occurs because of an unusually high rate of protein degradation, an unusually low rate of protein synthesis, or a combination of both. Muscle protein catabolism, whether caused by a high degree of protein degradation or a low degree of protein synthesis, leads to a decrease in muscle mass and to muscle wasting.

Muscle wasting is associated with chronic, neurological, genetic or infectious pathologies, diseases, illnesses or conditions. These include muscular dystrophies such as Duchenne muscular dystrophy and myotonic dystrophy; muscle atrophies such as post-polio muscle atrophy (PPMA); cachexias such as cardiac cachexia, aids cachexia and cancer cachexia, malnutrition, leprosy, diabetes, renal disease, chronic obstructive pulmonary disease (COPD), cancer, end stage renal failure, sarcopenia, emphysema, osteomalacia, HIV infection, AIDS, and cardiomyopathy.

In addition, other circumstances and conditions are linked to and can cause muscle wasting. These include chronic lower back pain, advanced age, central nervous system (CNS) injury, peripheral nerve injury, spinal cord injury, chemical injury, central nervous system (CNS) damage, peripheral nerve damage, spinal cord damage, chemical damage, burns, disuse deconditioning that occurs when a limb is immobilized, long term hospitalization due to illness or injury, and alcoholism.

An intact androgen receptor (AR) signaling pathway is crucial for appropriate development of skeletal muscles. Furthermore, an intact AR-signaling pathway increases lean muscle mass, muscle strength and muscle protein synthesis.

Muscle wasting, if left unabated, can have dire health consequences. For example, the changes that occur during muscle wasting can lead to a weakened physical state that is detrimental to an individual's health, resulting in increased susceptibility to bone fracture and poor physical performance status. In addition, muscle wasting is a strong predictor of morbidity and mortality in patients suffering from cachexia and AIDS.

New innovative approaches are urgently needed at both the basic science and clinical levels to develop compounds which are useful for a) male contraception; b) treatment of a variety of hormone-related conditions, for example conditions associated with Androgen Decline in Aging Male (ADAM), such as fatigue, depression, decreased libido, sexual dysfunction, erectile dysfunction, hypogonadism, osteoporosis, hair loss, anemia, obesity, sarcopenia, osteopenia, osteoporosis, benign prostate hyperplasia, alterations in mood and cognition and prostate cancer; c) treatment of conditions associated with ADIF, such as sexual dysfunction, decreased sexual libido, hypogonadism, sarcopenia, osteopenia, osteoporosis, alterations in cognition and mood, depression, anemia, hair loss, obesity, endometriosis, breast cancer, uterine cancer and ovarian cancer; d) treatment and/or prevention of chronic muscular wasting or sarcopenia; e) decreasing the incidence of, halting or causing a regression of prostate cancer; f) oral androgen replacement and/or other clinical therapeutic and/or diagnostic areas.

A wide variety of diseases and/or conditions are affected by hypogonadism, and catabolic effects, including kidney disease, central nervous system injuries, burns and chronic wounds.

In the United States (US), there is a rising incidence and prevalence of kidney failure. The number of patients enrolled in end-stage renal disease (ESRD) Medicare-funded programs has increased from approximately 10,000 beneficiaries in 1973 to 86,354 in 1983 and to 431,284 as of Dec. 31, 2002. In 2002 alone, 100,359 patients entered the US ESRD program. Chronic kidney disease (CKD) is a precursor to ESRD and occurs when the kidneys are not able to adequately remove wastes from the body. CKD is a slowly progressing disease, in which diabetes, hypertension and anemia may be co-morbid conditions.

CKD is diagnosed using a staging system that demonstrates the amount of kidney function available (stage 1=normal kidney function) and patients often do not present symptoms in the early stages. Stage 5 of CKD is ESRD, which is a complete or near complete failure of the kidneys and usually occurs when kidney function is less than 10% of baseline.

Accompanying symptoms associated with ESRD include hypogonadism, involuntary weight loss, fatigue and others.

Burns result in a testosterone reduction, nitrogen level reduction and a reduction in bone mineral density (BMD), which may persist even as long as one year following the injury and is associated with impaired wound healing, increased infection risks, erosion of lean body mass, hampered rehabilitation, and delayed reintegration of burn survivors into society. Catabolic effects initiated as a result of the burn lead to significant involuntary weight loss, further compounding the problem.

Spinal cord injuries (SCI) may result in the alteration central neurotransmitter secretion or production, which in turn may cause a hypothalamus-pituitary-adrenal axis dysfunction, leading to decreases in testosterone and other hormone levels. SCI or other acute illness or trauma characteristically includes heightened catabolism in conjunction with the lowered anabolic activity resulting in a condition that is prone to loss of lean body tissue. As long as the catabolic process goes uninterrupted, disturbed nutrient utilization will continue. The effects of the loss of lean body mass include the development of wounds and impaired healing mechanisms. Because of poor nutrition and protein combined with immobilization, patients with spinal cord injury are at high risk for bed sores.

Chronic wounds may be caused by any number of conditions, including diabetes, circulatory problems, immobilization and others. Compounding the problem, for example in diabetes, is the presence of neuropathy, which increases the risk of foot ulceration.

While there are many treatments and therapies for these conditions, none are ideal. Since the androgen receptor (AR) signaling pathway has been shown to increase lean muscle mass, muscle strength and muscle protein synthesis, and since hypogonadism accompanies these conditions, molecules targeting the AR signaling pathway may be useful in treating these diseases and/or conditions.

A determination is made whether the potential compound exhibits an antagonistic effect or an agonistic effect on the androgen receptor upon binding thereto, where the presence of said effect indicates the potential compound is a selective androgen receptor modulator.

Novel selective androgen receptor modulator platforms may be designed de novo inside the active site of the androgen receptor (AR). De novo design of SARM platforms utilizes techniques that progressively construct the ligand inside the active site of the androgen receptor and then score the results to rank which new ligands are the best for interacting with AR. De novo design utilizes many of the same conformational sampling algorithms and scoring functions as molecular docking. In addition to docking preconceived ligands into the receptor, modern computing provides for the generation of many thousands of de novo ligands, thereby virtually screening many compounds that would not be conceived by chemical intuition. In addition to de novo design, as described herein, the present invention may be used to virtually screen user-defined ligands using the concepts of molecular docking. The present invention also may be used to facilitate and augment pharmacore-based searches of molecule databases, such as the commercially available Available Chemical Database (ACD) or open source Zinc database. These techniques are implicitly directed at new template discovery since no preconceptions are given to the computer regarding ligand structure. A further advantage of the de novo approach as compared to virtual screening is that often the de novo leads are novel because the methodology is not searching pre-existing molecules or variants as in the traditional active analogue approach. It is contemplated that de novo designed SARMs could have new and improved tissue selectivities.

A “therapeutically effective amount” as used herein refers to that amount which provides a therapeutic effect for a given condition and administration regimen.

As used herein, the term “administering” refers to bringing a subject in contact with a compound of the present invention. As used herein, administration can be accomplished in vitro, i.e. in a test tube, or in vivo, i.e. in cells or tissues of living organisms, for example humans. In one embodiment, the present invention encompasses administering the compounds of the present invention to a subject.

The pharmaceutical compositions containing the compounds of this invention can be administered to a subject by any method known to a person skilled in the art, such as orally, parenterally, intravascularly, paracancerally, transmucosally, transdermally, intramuscularly, intranasally, intravenously, intradermally, subcutaneously, sublingually, intraperitonealy, intraventricularly, intracranially, intravaginally, by inhalation, rectally, intratumorally, or by any means in which the recombinant virus/composition can be delivered to tissue (e.g., needle or catheter). Alternatively, topical administration may be desired for application to mucosal cells, for skin or ocular application. Another method of administration is via aspiration or aerosol formulation.

In one embodiment, the pharmaceutical compositions are administered orally, and are thus formulated in a form suitable for oral administration, i.e. as a solid or a liquid preparation. Suitable solid oral formulations include tablets, capsules, pills, granules, pellets, powders, and the like. Suitable liquid oral formulations include solutions, suspensions, dispersions, emulsions, oils and the like. In one embodiment of the present invention, the SARM compounds are formulated in a capsule. In accordance with this embodiment, the compositions of the present invention comprise in addition to a compound of this invention and the inert carrier or diluent, a hard gelatin capsule.

In one embodiment, the micronized capsules comprise particles containing a compound of this invention, wherein the term “micronized” used herein refers to particles having a particle size of less than 100 microns, or in another embodiment, less than 60 microns, or in another embodiment, less than 36 microns, or in another embodiment, less than 16 microns, or in another embodiment, less than 10 microns, or in another embodiment, less than 6 microns.

Further, in another embodiment, the pharmaceutical compositions are administered by intravenous, intraarterial, or intramuscular injection of a liquid preparation. Suitable liquid formulations include solutions, suspensions, dispersions, emulsions, oils and the like. In one embodiment, the pharmaceutical compositions are administered intravenously, and are thus formulated in a form suitable for intravenous administration. In another embodiment, the pharmaceutical compositions are administered intraarterially, and are thus formulated in a form suitable for intraarterial administration. In another embodiment, the pharmaceutical compositions are administered intramuscularly, and are thus formulated in a form suitable for intramuscular administration.

Further, in another embodiment, the pharmaceutical compositions are administered topically to body surfaces, and are thus formulated in a form suitable for topical administration. Suitable topical formulations include gels, ointments, creams, lotions, drops and the like. For topical administration, the compounds of this invention or their physiologically tolerated derivatives such as salts, esters, N-oxides, and the like are prepared and applied as solutions, suspensions, or emulsions in a physiologically acceptable diluent with or without a pharmaceutical carrier.

Further, in another embodiment, the pharmaceutical compositions are administered as a suppository, for example a rectal suppository or a urethral suppository. Further, in another embodiment, the pharmaceutical compositions are administered by subcutaneous implantation of a pellet. In a further embodiment, the pellet provides for controlled release of a compound as herein described over a period of time. In a further embodiment, the pharmaceutical compositions are administered intravaginally.

In another embodiment, the active compound can be delivered in a vesicle, in particular a liposome (see Langer, Science 249:1627-1633 (1990); Treat et al., in Liposomes in the Therapy of Infectious Disease and Cancer, Lopez-Berestein and Fidler (eds.), Liss, New York, pp. 363-366 (1989); Lopez-Berestein, ibid., pp. 317-327; see generally ibid).

As used herein “pharmaceutically acceptable carriers or diluents” are well known to those skilled in the art. The carrier or diluent may be a solid carrier or diluent for solid formulations, a liquid carrier or diluent for liquid formulations, or mixtures thereof.

Solid carriers/diluents include, but are not limited to, a gum, a starch (e.g. corn starch, pregeletanized starch), a sugar (e.g., lactose, mannitol, sucrose, dextrose), a cellulosic material (e.g. microcrystalline cellulose), an acrylate (e.g. polymethylacrylate), calcium carbonate, magnesium oxide, talc, or mixtures thereof.

In one embodiment, the compositions of this invention may include, a compound of this invention or any combination thereof, together with one or more pharmaceutically acceptable excipients.

It is to be understood that this invention encompasses any embodiment of a compound as described herein, which in some embodiments is referred to as “a compound of this invention”.

Suitable excipients and carriers may be, according to embodiments of the invention, solid or liquid and the type is generally chosen based on the type of administration being used. Liposomes may also be used to deliver the composition. Examples of suitable solid carriers include lactose, sucrose, gelatin and agar. Oral dosage forms may contain suitable binders, lubricants, diluents, disintegrating agents, coloring agents, flavoring agents, flow-inducing agents, and melting agents. Liquid dosage forms may contain, for example, suitable solvents, preservatives, emulsifying agents, suspending agents, diluents, sweeteners, thickeners, and melting agents. Parenteral and intravenous forms should also include minerals and other materials to make them compatible with the type of injection or delivery system chosen. Of course, other excipients may also be used.

For liquid formulations, pharmaceutically acceptable carriers may be aqueous or non-aqueous solutions, suspensions, emulsions or oils. Examples of non-aqueous solvents are propylene glycol, polyethylene glycol, and injectable organic esters such as ethyl oleate. Aqueous carriers include water, alcoholic/aqueous solutions, cyclodextrins, emulsions or suspensions, including saline and buffered media. Examples of oils are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, mineral oil, olive oil, sunflower oil, and fish-liver oil.

Parenteral vehicles (for subcutaneous, intravenous, intraarterial, or intramuscular injection) include sodium chloride solution, Ringer's dextrose, dextrose and sodium chloride, lactated Ringer's and fixed oils. Intravenous vehicles include fluid and nutrient replenishers, electrolyte replenishers such as those based on Ringer's dextrose, and the like. Examples are sterile liquids such as water and oils, with or without the addition of a surfactant and other pharmaceutically acceptable adjuvants. In general, water, saline, aqueous dextrose and related sugar solutions, and glycols such as propylene glycols or polyethylene glycol are preferred liquid carriers, particularly for injectable solutions. Examples of oils are those of petroleum, animal, vegetable, or synthetic origin, for example, peanut oil, soybean oil, mineral oil, olive oil, sunflower oil, and fish-liver oil.

In addition, the compositions may further comprise binders (e.g. acacia, cornstarch, gelatin, carbomer, ethyl cellulose, guar gum, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, povidone), disintegrating agents (e.g. cornstarch, potato starch, alginic acid, silicon dioxide, croscarmelose sodium, crospovidone, guar gum, sodium starch glycolate), buffers (e.g., Tris-HCl, acetate, phosphate) of various pH and ionic strength, additives such as albumin or gelatin to prevent absorption to surfaces, detergents (e.g., Tween 20, Tween 80, Pluronic F68, bile acid salts), protease inhibitors, surfactants (e.g. sodium lauryl sulfate), permeation enhancers, solubilizing agents (e.g., cremophor, glycerol, polyethylene glycerol, benzlkonium chloride, benzyl benzoate, cyclodextrins, sobitan esters, stearic acids), anti-oxidants (e.g., ascorbic acid, sodium metabisulfite, butylated hydroxyanisole), stabilizers (e.g. hydroxypropyl cellulose, hyroxypropylmethyl cellulose), viscosity increasing agents (e.g. carbomer, colloidal silicon dioxide, ethyl cellulose, guar gum), sweeteners (e.g. aspartame, citric acid), preservatives (e.g., Thimerosal, benzyl alcohol, parabens), coloring agents, lubricants (e.g. stearic acid, magnesium stearate, polyethylene glycol, sodium lauryl sulfate), flow-aids (e.g. colloidal silicon dioxide), plasticizers (e.g. diethyl phthalate, triethyl citrate), emulsifiers (e.g. carbomer, hydroxypropyl cellulose, sodium lauryl sulfate), polymer coatings (e.g., poloxamers or poloxamines), coating and film forming agents (e.g. ethyl cellulose, acrylates, polymethacrylates), and/or adjuvants.

In one embodiment, the pharmaceutical compositions provided herein are controlled release compositions, i.e. compositions in which the compound of this invention is released over a period of time after administration. Controlled or sustained release compositions include formulation in lipophilic depots (e.g. fatty acids, waxes, oils). In another embodiment, the composition is an immediate release composition, i.e. a composition in which the whole quantity of the compound is released immediately after administration.

In yet another embodiment, the pharmaceutical composition can be delivered in a controlled release system. For example, the agent may be administered using intravenous infusion, an implantable osmotic pump, a transdermal patch, liposomes, or other modes of administration. In one embodiment, a pump may be used (see Langer, supra; Sefton, CRC Crit. Ref. Biomed. Eng. 14:201 (1987); Buchwald et al., Surgery 88:607 (1980); Saudek et al., N. Engl. J. Med. 321:674 (1989). In another embodiment, polymeric materials can be used. In yet another embodiment, a controlled release system can be placed in proximity to the therapeutic target, i.e., the brain, thus requiring only a fraction of the systemic dose (see, e.g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 116-138 (1984). Other controlled release systems are discussed in the review by Langer (Science 249:1627-1633 (1990).

The compositions may also include incorporation of the active material into or onto particulate preparations of polymeric compounds such as polylactic acid, polglycolic acid, hydrogels, etc., or onto liposomes, microemulsions, micelles, unilamellar or multilamellar vesicles, erythrocyte ghosts, or spheroplasts. Such compositions will influence the physical state, solubility, stability, rate of in vivo release, and rate of in vivo clearance.

Also comprehended by the invention are particulate compositions coated with polymers (e.g. poloxamers or poloxamines) and the compound coupled to antibodies directed against tissue-specific receptors, ligands or antigens or coupled to ligands of tissue-specific receptors.

Also comprehended by the invention are compounds modified by the covalent attachment of water-soluble polymers such as polyethylene glycol, copolymers of polyethylene glycol and polypropylene glycol, carboxymethyl cellulose, dextran, polyvinyl alcohol, polyvinylpyrrolidone or polyproline. The modified compounds are known to exhibit substantially longer half-lives in blood following intravenous injection than do the corresponding unmodified compounds (Abuchowski et al., 1981; Newmark et al., 1982; and Katre et al., 1987). Such modifications may also increase the compound's solubility in aqueous solution, eliminate aggregation, enhance the physical and chemical stability of the compound, and greatly reduce the immunogenicity and reactivity of the compound. As a result, the desired in vivo biological activity may be achieved by the administration of such polymer-compound abducts less frequently or in lower doses than with the unmodified compound.

The preparation of pharmaceutical compositions which contain an active component is well understood in the art, for example by mixing, granulating, or tablet-forming processes. The active therapeutic ingredient is often mixed with excipients which are pharmaceutically acceptable and compatible with the active ingredient. For oral administration, the compounds of this invention or their physiologically tolerated derivatives such as salts, esters, N-oxides, and the like are mixed with additives customary for this purpose, such as vehicles, stabilizers, or inert diluents, and converted by customary methods into suitable forms for administration, such as tablets, coated tablets, hard or soft gelatin capsules, aqueous, alcoholic or oily solutions. For parenteral administration, the compounds of this invention or their physiologically tolerated derivatives such as salts, esters, N-oxides, and the like are converted into a solution, suspension, or emulsion, if desired with the substances customary and suitable for this purpose, for example, solubilizers or other.

An active component can be formulated into the composition as neutralized pharmaceutically acceptable salt forms. Pharmaceutically acceptable salts include the acid addition salts (formed with the free amino groups of the polypeptide or antibody molecule), which are formed with inorganic acids such as, for example, hydrochloric or phosphoric acids, or such organic acids as acetic, oxalic, tartaric, mandelic, and the like. Salts formed from the free carboxyl groups can also be derived from inorganic bases such as, for example, sodium, potassium, ammonium, calcium, or ferric hydroxides, and such organic bases as isopropylamine, trimethylamine, 2-ethylamino ethanol, histidine, procaine, and the like.

For use in medicine, the salts of the compound will be pharmaceutically acceptable salts. Other salts may, however, be useful in the preparation of the compounds according to the invention or of their pharmaceutically acceptable salts. Suitable pharmaceutically acceptable salts of the compounds of this invention include acid addition salts which may, for example, be formed by mixing a solution of the compound according to the invention with a solution of a pharmaceutically acceptable acid such as hydrochloric acid, sulphuric acid, methanesulphonic acid, fumaric acid, maleic acid, succinic acid, acetic acid, benzoic acid, oxalic acid, citric acid, tartaric acid, carbonic acid or phosphoric acid.

BPH occurs in over 75% of men over 50 years of age, reaching 88% prevalence by the ninth decade. BPH frequently results in a gradual squeezing of the portion of the urethra which traverses the prostate (prostatic urethra). This causes patients to experience a frequent urge to urinate because of incomplete emptying of the bladder and urgency of urination. The obstruction of urinary flow can also lead to a general lack of control over urination, including difficulty initiating urination when desired, as well as difficulty in preventing urinary flow because of the inability to empty urine from the bladder, a condition known as overflow urinary incontinence, which can lead to urinary obstruction and to urinary failure.

“Osteoporosis” refers, in one embodiment, to a thinning of the bones with reduction in bone mass due to depletion of calcium and bone protein. In another embodiment, osteoporosis is a systemic skeletal disease, characterized by low bone mass and deterioration of bone tissue, with a consequent increase in bone fragility and susceptibility to fracture. In osteoporotic patients, bone strength is abnormal, in one embodiment, with a resulting increase in the risk of fracture. In another embodiment, osteoporosis depletes both the calcium and the protein collagen normally found in the bone, in one embodiment, resulting in either abnormal bone quality or decreased bone density. In another embodiment, bones that are affected by osteoporosis can fracture with only a minor fall or injury that normally would not cause a bone fracture. The fracture can be, in one embodiment, either in the form of cracking (as in a hip fracture) or collapsing (as in a compression fracture of the spine). The spine, hips, and wrists are common areas of osteoporosis-induced bone fractures, although fractures can also occur in other skeletal areas. Unchecked osteoporosis can lead, in another embodiment, to changes in posture, physical abnormality, and decreased mobility.

In another embodiment, the administering step includes intravenously, intraarterially, or intramuscularly injecting to said subject said pharmaceutical composition in liquid form; subcutaneously implanting in said subject a pellet containing said pharmaceutical composition; orally administering to said subject said pharmaceutical composition in a liquid or solid form; or topically applying to the skin surface of said subject said pharmaceutical composition.

A muscle is a tissue of the body that primarily functions as a source of power. There are three types of muscles in the body: a) skeletal muscle—the muscle responsible for moving extremities and external areas of the bodies; b) cardiac muscle—the heart muscle; and c) smooth muscle—the muscle that is in the walls of arteries and bowel.

A wasting condition or disorder is defined herein as a condition or disorder that is characterized, at least in part, by an abnormal, progressive loss of body, organ or tissue mass. A wasting condition can occur as a result of a pathology such as, for example, cancer, or an infection, or it can be due to a physiologic or metabolic state, such as disuse deconditioning that can occur, for example, due to prolonged bed rest or when a limb is immobilized, such as in a cast. A wasting condition can also be age associated. The loss of body mass that occurs during a wasting condition can be characterized by a loss of total body weight, or a loss of organ weight such as a loss of bone or muscle mass due to a decrease in tissue protein.

In one embodiment, “muscle wasting” or “muscular wasting”, used herein interchangeably, refer to the progressive loss of muscle mass and/or to the progressive weakening and degeneration of muscles, including the skeletal or voluntary muscles which control movement, cardiac muscles which control the heart, and smooth muscles. In one embodiment, the muscle wasting condition or disorder is a chronic muscle wasting condition or disorder. “Chronic muscle wasting” is defined herein as the chronic (i.e. persisting over a long period of time) progressive loss of muscle mass and/or to the chronic progressive weakening and degeneration of muscle.

The loss of muscle mass that occurs during muscle wasting can be characterized by a muscle protein breakdown or degradation, by muscle protein catabolism. Protein catabolism occurs because of an unusually high rate of protein degradation, an unusually low rate of protein synthesis, or a combination of both. Protein catabolism or depletion, whether caused by a high degree of protein degradation or a low degree of protein synthesis, leads to a decrease in muscle mass and to muscle wasting. The term “catabolism” has its commonly known meaning in the art, specifically an energy burning form of metabolism.

Muscle wasting can occur as a result of a pathology, disease, condition or disorder. In one embodiment, the pathology, illness, disease or condition is chronic. In another embodiment, the pathology, illness, disease or condition is genetic. In another embodiment, the pathology, illness, disease or condition is neurological. In another embodiment, the pathology, illness, disease or condition is infectious. As described herein, the pathologies, diseases, conditions or disorders for which the compounds and compositions of the present invention are administered are those that directly or indirectly produce a wasting (i.e. loss) of muscle mass, that is a muscle wasting disorder.

In one embodiment, muscle wasting in a subject is a result of the subject having a muscular dystrophie; muscle atrophy; X-linked spinal-bulbar muscular atrophy (SBMA).

The muscular dystrophies are genetic diseases characterized by progressive weakness and degeneration of the skeletal or voluntary muscles that control movement. The muscles of the heart and some other involuntary muscles are also affected in some forms of muscular dystrophy. The major forms of muscular dystrophy (MD) are: duchenne muscular dystrophy, myotonic dystrophy, duchenne muscular dystrophy, becker muscular dystrophy, limb-girdle muscular dystrophy, facioscapulhumeral muscular dystrophy, congenital muscular dystrophy, oculopharyngeal muscular dystrophy, distal muscular dystrophy and emery-dreifuss muscular dystrophy.

Muscular dystrophy can affect people of all ages. Although some forms first become apparent in infancy or childhood, others may not appear until middle age or later. Duchenne MD is the most common form, typically affecting children. Myotonic dystrophy is the most common of these diseases in adults.

Muscle atrophy (MA) is characterized by wasting away or diminution of muscle and a decrease in muscle mass. For example, Post-Polio MA is a muscle wasting that occurs as part of the post-polio syndrome (PPS). The atrophy includes weakness, muscle fatigue, and pain.

Another type of MA is X-linked spinal-bulbar muscular atrophy (SBMA—also known as Kennedy's Disease). This disease arises from a defect in the androgen receptor gene on the X chromosome, affects only males, and its onset is in adulthood. Because the primary disease cause is an androgen receptor mutation, androgen replacement is not a current therapeutic strategy. There are some investigational studies where exogenous testosterone propionate is being given to boost the levels of androgen with hopes of overcoming androgen insensitivity and perhaps provide an anabolic effect. Still, use of supraphysiological levels of testosterone for supplementation will have limitations and other potentially serious complications.

Sarcopenia is a debilitating disease that afflicts the elderly and chronically ill patients and is characterized by loss of muscle mass and function. Further, increased lean body mass is associated with decreased morbidity and mortality for certain muscle-wasting disorders. In addition, other circumstances and conditions are linked to, and can cause muscle wasting disorders. For example, studies have shown that in severe cases of chronic lower back pain, there is paraspinal muscle wasting.

Muscle wasting and other tissue wasting is also associated with advanced age. It is believed that general weakness in old age is due to muscle wasting. As the body ages, an increasing proportion of skeletal muscle is replaced by fibrous tissue. The result is a significant reduction in muscle power, performance and endurance.

Long term hospitalization due to illness or injury, or disuse deconditioning that occurs, for example, when a limb is immobilized, can also lead to muscle wasting, or wasting of other tissue. Studies have shown that in patients suffering injuries, chronic illnesses, burns, trauma or cancer, who are hospitalized for long periods of time, there is a long-lasting unilateral muscle wasting, and a decrease in body mass.

Injuries or damage to the central nervous system (CNS) are also associated with muscle wasting and other wasting disorders. Injuries or damage to the CNS can be, for example, caused by diseases, trauma or chemicals. Examples are central nerve injury or damage, peripheral nerve injury or damage and spinal cord injury or damage. In one embodiment CNS damage or injury comprise Alzheimer's diseases (AD); anger (mood); anorexia, anorexia nervosa, anorexia associated with aging and/or assertiveness (mood).

In another embodiment, muscle wasting or other tissue wasting may be a result of alcoholism, and may be treated with the compounds and compositions of the invention, representing embodiments thereof.

In one embodiment, the invention provides a use of a compound as described herein or its analog, isomer, metabolite, derivative, pharmaceutically acceptable salt, pharmaceutical product, polymorph, crystal, impurity, N-oxide, hydrate or any combination thereof, for the treatment of a wasting disease, disorder or condition in a subject.

In one embodiment, the wasting disease, disorder or condition being treated is associated with chronic illness

This invention is directed to treating, in some embodiments, any wasting disorder, which may be reflected in muscle wasting, weight loss, malnutrition, starvation, or any wasting or loss of functioning due to a loss of tissue mass.

In some embodiments, wasting diseases or disorders, such as cachexia; malnutrition, tuberculosis, leprosy, diabetes, renal disease, chronic obstructive pulmonary disease (COPD), cancer, end stage renal failure, sarcopenia, emphysema, osteomalacia, or cardiomyopathy, may be treated by the methods of this invention, via the administration of a SARM compound as herein described, compositions comprising the same, with or without additional drugs, compounds, or agents, which provide a therapeutic effect for the condition being treated.

In some embodiments, wasting is due to infection with enterovirus, Epstein-Barr virus, herpes zoster, HIV, trypanosomes, influenze, coxsackie, rickettsia, trichinella, schistosoma or mycobacteria, and this invention, in some embodiments, provides methods of treatment thereof.

Cachexia is weakness and a loss of weight caused by a disease or as a side effect of illness. Cardiac cachexia, i.e. a muscle protein wasting of both the cardiac and skeletal muscle, is a characteristic of congestive heart failure. Cancer cachexia is a syndrome that occurs in patients with solid tumors and hematological malignancies and is manifested by weight loss with massive depletion of both adipose tissue and lean muscle mass.

Cachexia is also seen in acquired immunodeficiency syndrome (ADS), human immunodeficiency virus (HIV)-associated myopathy and/or muscle weakness/wasting is a relatively common clinical manifestation of AIDS. Individuals with HIV-associated myopathy or muscle weakness or wasting typically experience significant weight loss, generalized or proximal muscle weakness, tenderness, and muscle atrophy.

In some embodiments, cranial nerve diseases comprise bell palsy, cranial nerve diseases, facial hemiatrophy, facial neuralgia, glossopharyngeal nerve diseases, Moebius syndrome, or trigeminal neuralgia.

In some embodiments, central nervous system diseases comprise injuries or damage to the central nervous system (CNS). In some embodiments, injuries or damage to the CNS may be associated with muscle wasting disorders. Injuries or damage to the CNS can be, for example, caused by diseases, trauma or chemicals. Examples are central nerve injury or damage, peripheral nerve injury or damage and spinal cord injury or damage.

Studies involving patients with spinal cord injuries (SCI) have shown that central neurotransmitters may be altered after SCI causing hypothalamus-pituitary-adrenal axis dysfunction, whose disruption led to a significant decrease in testosterone and other hormone levels. SCI or other acute illness or trauma characteristically includes heightened catabolism in conjunction with the lowered anabolic activity resulting in a condition that is prone to loss of lean body tissue, which is often accompanied by disturbed nutrient utilization. The effects of the loss of lean body mass include the development of wounds and impaired healing mechanisms, further compounding the problem. Because of poor nutrition and protein catabolism combined with immobilization, patients with spinal cord injury are at high risk for bed sores.

In one embodiment, a wide variety of injuries of the CNS may be treated by the methods of the present invention. CNS injury may refer, in one embodiment, to a breakdown of the membrane of a nerve cell, or, in another embodiment, to the inability of the nerve to produce and propagate nerve impulses, or in another embodiment, to the death of the cell. An injury includes damage that directly or indirectly affects the normal functioning of the CNS. The injury may be a structural, physical, or mechanical impairment and may be caused by physical impact, as in the case of a crushing, compression, or stretching of nerve fibers. Alternatively, the cell membrane may be destroyed by or degraded by an illness, a chemical imbalance, or a physiological malfunction such as anoxia (e.g., stroke), aneurysm, or reperfusion. A CNS injury includes, for example and without limitation, damage to retinal ganglion cells, a traumatic brain injury, a stroke-related injury, a cerebral aneurism-related injury, a spinal cord injury, including monoplegia, diplegia, paraplegia, hemiplegia and quadriplegia, a neuroproliferative disorder, or neuropathic pain syndrome.

With injury to the spinal cord of a mammal, connections between nerves in the spinal cord are broken. Such injuries block the flow of nerve impulses for the nerve tracts affected by the injury, with a resulting impairment to both sensory and motor function. Injuries to the spinal cord may arise from compression or other contusion of the spinal cord, or a crushing or severing of the spinal cord. A severing of the spinal cord, also referred to herein as a “transection,” may be a complete severing or, may be an incomplete severing of the spinal cord.

In some embodiments, the methods of treating a subject suffering form a CNS injury or, in other embodiments, spinal cord injury, may be accompanied by treatment of the subject with electrical stimulation of the injured site and the administration of a purine nucleoside, or analog thereof, for example as described in United States Patent Application Publication Number 20040214790A1.

In one embodiment, the dermatological disorder is a wound or a burn. In some embodiments, wounds and/or ulcers are found protruding from the skin or on a mucosal surface or as a result of an infarction in an organ. A wound may be a result of a soft tissue defect or a lesion or of an underlying condition. In one embodiment, the term “wound” denotes a bodily injury with disruption of the normal integrity of tissue structures. The term is also intended to encompass the terms “sore”, “lesion”, “necrosis” and “ulcer”. In one embodiment, the term “sore” refers to any lesion of the skin or mucous membranes and the term “ulcer” refers to a local defect, or excavation, of the surface of an organ or tissue, which is produced by the sloughing of necrotic tissue. Lesion generally relates to any tissue defect. Necrosis is related to dead tissue resulting from infection, injury, inflammation or infarctions. All of these are encompassed by the term “wound”, which denotes any wound at any particular stage in the healing process including the stage before any healing has initiated or even before a specific wound like a surgical incision is made (prophylactic treatment).

Examples of wounds which can be prevented and/or treated in accordance with the present invention are, e.g., aseptic wounds, contused wounds, incised wounds, lacerated wounds, non-penetrating wounds (i.e. wounds in which there is no disruption of the skin but there is injury to underlying structures), open wounds, penetrating wounds, perforating wounds, puncture wounds, septic wounds, subcutaneous wounds, etc. Examples of sores are bed sores, canker sores, chrome sores, cold sores, pressure sores etc. Examples of ulcers are, e.g., peptic ulcer, duodenal ulcer, gastric ulcer, gouty ulcer, diabetic ulcer, hypertensive ischemic ulcer, stasis ulcer, ulcus cruris (venous ulcer), sublingual ulcer, submucous ulcer, symptomatic ulcer, trophic ulcer, tropical ulcer, veneral ulcer, e.g. caused by gonorrhoea (including urethritis, endocervicitis and proctitis). Conditions related to wounds or sores which may be successfully treated according to the invention are burns, anthrax, tetanus, gas gangrene, scalatina, erysipelas, sycosis barbae, folliculitis, impetigo contagiosa, or impetigo bullosa, etc. There is often a certain overlap between the use of the terms “wound” and “ulcer” and “wound” and “sore” and, furthermore, the terms are often used at random. Therefore as mentioned above, in the present context the term “wounds” encompasses the term “ulcer”, “lesion”, “sore” and “infarction”, and the terms are indiscriminately used unless otherwise indicated.

The kinds of wounds to be treated according to the invention include also i) general wounds such as, e.g., surgical, traumatic, infectious, ischemic, thermal, chemical and bullous wounds; ii) wounds specific for the oral cavity such as, e.g., post-extraction wounds, endodontic wounds especially in connection with treatment of cysts and abscesses, ulcers and lesions of bacterial, viral or autoimmunological origin, mechanical, chemical, thermal, infectious and lichenoid wounds; herpes ulcers, stomatitis aphthosa, acute necrotising ulcerative gingivitis and burning mouth syndrome are specific examples; and iii) wounds on the skin such as, e.g., neoplasm, burns (e.g. chemical, thermal), lesions (bacterial, viral, autoimmunological), bites and surgical incisions. Another way of classifying wounds is as i) small tissue loss due to surgical incisions, minor abrasions and minor bites, or as ii) significant tissue loss. The latter group includes ischemic ulcers, pressure sores, fistulae, lacerations, severe bites, thermal burns and donor site wounds (in soft and hard tissues) and infarctions.

In other aspects of the invention, the wound to be prevented and/or treated is selected from the group consisting of aseptic wounds, infarctions, contused wounds, incised wounds, lacerated wounds, non-penetrating wounds, open wounds, penetrating wounds, perforating wounds, puncture wounds, septic wounds and subcutaneous wounds.

Other wounds which are of importance in connection with the present invention are wounds like ischemic ulcers, pressure sores, fistulae, severe bites, thermal burns and donor site wounds.

In one embodiment, the compound as described herein is useful in wound healing as an adjunct to physical therapy/rehabilitation, or as an anabolic agent. In another embodiment, the compound as described herein is useful in promoting healing of anterior cruciate ligament (ACL) or medial cruciate ligament (MCL) injuries, or accelerating recovery after ACL or MCL surgery. In another embodiment, the compound as described herein is useful in enhancing athletic performance. In another embodiment, the compound as described herein is useful in treating burns. In another embodiment, the compound as described herein is useful in stimulating cartilage regrowth. In another embodiment, the compound as described herein is useful in preventing, treating, or reversing of catabolism associated with prolonged critical illness, pulmonary dysfunction, ventilator dependency, aging, AIDS, trauma, surgery, congestive heart failure, cardiac myopathy, burns, cancer, COPD. In another embodiment, the compound as described herein is useful in preventing or reversing protein catabolism due to trauma. In another embodiment, the compound as described herein is useful as a) adjunct to cauterization therapy (laser or radio) as is used in surgery to promote wound healing, b) adjunct to cryotherapy to promote wound healing, c)

adjunct to chemotherapy to prevent side effects such as alopecia, hypogonadism, muscle wasting, osteopenia, osteoporosis, sarcopenia, increased LDL, triglyceride (TG) or total cholesterol, decreased HDL. In another embodiment, the compound as described herein is useful in a chronic catabolic state (coma, wasting conditions, starvation, eating disorders); concomitant bone fracture and muscle damage; critical illness in which muscle or bone wasting are apparent; and/or connective tissue diseases and disorders.

Ischemic ulcers and pressure sores are wounds, which normally only heal very slowly and especially in such cases an improved and more rapid healing is of course of great importance for the patient. Furthermore, the costs involved in the treatment of patients suffering from such wounds are markedly reduced when the healing is improved and takes place more rapidly.

Donor site wounds are wounds which e.g. occur in connection with removal of hard tissue from one part of the body to another part of the body e.g. in connection with transplantation. The wounds resulting from such operations are very painful and an improved healing is therefore most valuable.

The term “skin” is used in a very broad sense embracing the epidermal layer of the skin and in those cases where the skin surface is more or less injured also the dermal layer of the skin. Apart from the stratum corneum, the epidermal layer of the skin is the outer (epithelial) layer and the deeper connective tissue layer of the skin is called the dermis.

In some embodiments, burns are associated with reduced testosterone levels, and hypogonadism is associated with delayed wound healing. In one embodiment, the methods of this invention provide for treating a subject suffering from a wound or a burn.

In some embodiments, the present invention provides a method for promoting healing of anterior cruciate ligament (ACL) or medial cruciate ligament (MCL) injuries, or accelerating recovery after ACL or MCL surgery.

In one embodiment, the methods of this invention are useful in subjects predisposed to kidney diseases or disorders. In one embodiment, the phrase “predisposed to a kidney disease or disorder” with respect to a subject is synonymous with the phrase “subject at risk”, and includes a subject at risk of acute or chronic renal failure, or at risk of the need for renal replacement therapy, if the subject is reasonably expected to suffer a progressive loss of renal function associated with progressive loss of functioning nephron units. Whether a particular subject is at risk is a determination which may routinely be made by one of ordinary skill in the relevant medical or veterinary art.

In one embodiment, subjects with kidney disease, in particular male subjects with end-stage renal disease (ESRD) suffer from hypogonadism, with some having concomitant moderate to severe protein-energy malnutrition (PEM), which leads to higher required doses of erythropoietin (EPO), lower quality of life (QOL) scores, and higher mortality. Many have other symptoms associated with hypogonadism, including fatigue, lack of apetite, muscle weakness, etc. In some embodiments, the treatment methods of this invention are useful in treating symptoms associated with hypogonadism, brought about in the subject by androgen deficiency in a female (ADM); androgen deficiency in aging male (ADAM) to include fatigue, depression, decreased libido, erectile dysfunction, decreased cognition, decreased mood; androgen insufficiency (male or female), androgen deficiency (male or female).

In one embodiment, diabetic nephropathy is a complication of diabetes that evolves early, typically before clinical diagnosis of diabetes is made. The earliest clinical evidence of nephropathy is the appearance of low but abnormal levels (>30 mg/day or 20 μg/min) of albumin in the urine (microalbuminuria), followed by albuminuria (>300 mg/24 h or 200 μg/min) that develops over a period of 10-15 years. In patients with type 1 diabetes, diabetic hypertension typically becomes manifest early on, by the time that patients develop microalbuminuria. Once overt nephropathy occurs, the glomerular filtration rate (GFR) falls over a course of times, which may be several years, resulting in end stage renal disease (ESRD) in diabetic individuals.

Hypertension is another comorbid factor for renal disease. In some embodiments, treatment of renal disease according to the present invention may comprise concomitant treatment with a compound of this invention and an agent which treats hypertension.

A wasting condition or disorder is defined herein as a condition or disorder that is characterized, at least in part, by an abnormal, progressive loss of body, organ or tissue mass. A wasting condition can occur as a result of a pathology such as, for example, cancer, or it can be due to a physiologic or metabolic state, such as disuse deconditioning that can occur, for example, due to prolonged bed rest or when a limb is immobilized, such as in a cast, or with the occurrence of multiple wounds, including, for example, amputation, as occurs in diabetics, and other conditions, as will be appreciated by one skilled in the art. A wasting condition can also be age associated. The loss of body mass that occurs during a wasting condition can be characterized by a loss of total body weight, or a loss of organ weight such as a loss of bone or muscle mass due to a decrease in tissue protein.

In one embodiment, the terms “muscle wasting” or “muscular wasting”, refer to the progressive loss of muscle mass and/or to the progressive weakening and degeneration of muscles, including the skeletal or voluntary muscles which control movement, cardiac muscles which control the heart, and smooth muscles. In one embodiment, the muscle wasting condition or disorder is a chronic muscle wasting condition or disorder. “Chronic muscle wasting” is defined herein as the chronic (i.e. persisting over a long period of time) progressive loss of muscle mass and/or to the chronic progressive weakening and degeneration of muscle.

The loss of muscle mass that occurs during muscle wasting can be characterized by a muscle protein breakdown or degradation, by muscle protein catabolism. Protein catabolism occurs because of an unusually high rate of protein degradation, an unusually low rate of protein synthesis, or a combination of both. Protein catabolism or depletion, whether caused by a high degree of protein degradation or a low degree of protein synthesis, leads to a decrease in muscle mass and to muscle wasting. The term “catabolism” has its commonly known meaning in the art, specifically an energy burning form of metabolism.

Muscle wasting can occur as a result of pathology, disease, condition or disorders, including disorders for treatment via the methods of this invention, such as, for example, end stage renal failure.

In some embodiments, the present invention provides a method for prevention of statin induced rhabdomyolysis.

In one embodiment, the present invention provides a method of treating, preventing, inhibiting, reducing or suppressing protein catabolism in a subject suffering from a kidney disease or disorder,

Cachexia is weakness and a loss of weight caused by a disease or as a side effect of illness. Long term hospitalization due to illness or injury, or disuse deconditioning that occurs, for example, when a limb is immobilized, can also lead to muscle wasting. Studies have shown that in patients suffering injuries, chronic illnesses, burns, trauma or cancer, who are hospitalized for long periods of time, there is a long-lasting unilateral muscle wasting, with a consequent decrease in body mass. Nervous system injury, for example, spinal cord injury, as described further herein, may be a contributory factor, as well.

Example 5 demonstrates that a compound of formula (I) is anabolic yet minimally androgenic, thus such compounds may be useful in treating patient groups in which androgens were contraindicated in the past. Compound of formula (I) was shown to stimulate muscle growth, whether in the presence or absence of testosterone while exerting anti-proliferative effects on the prostate, thus, in one embodiment, the methods of this invention provide for restoring lost muscle mass in patients with sarcopenia or cachexia.

In one embodiment, the compounds as herein described alter the levels of leptin in a subject. In another embodiment, the compounds as herein described decrease the levels of leptin. In another embodiment, the compounds as herein described increase the levels of leptin in a subject. Leptin is known to have an effect on appetite on weight loss in obese mice, and thus has been implicated in obesity.

The compounds as herein described, in one embodiment, affect circulating, or in another embodiment, tissue levels of leptin. In one embodiment, the term ‘level/s of leptin’ refers to the serum level of leptin. As contemplated herein, the compounds of the present invention have an effect on leptin in-vitro and in-vivo. Leptin levels can be measured by methods known to one skilled in the art, for example by commercially available ELISA kits. In addition, Leptin levels may be determined in in-vitro assays, or in in-vivo assays, by any method known to a person skilled in the art.

Since leptin is implicated in controlling appetite, weight loss, food intake, and energy expenditure, modulating and/or controlling the levels of leptin is a useful therapeutic approach in treating preventing, inhibiting or reducing the incidence of obesity in subjects suffering from obesity. Modulating the level of leptin can result in a loss of appetite, a reduction of food intake, and an increase in energy expenditure in the subject, and thus may contribute to the control and treatment of obesity.

Non-limiting examples of such a disorder are osteoarthritis, Type II diabetes mellitus, increased blood pressure, stroke, and heart disease.

Cholesterol, triacylglycerol and other lipids are transported in body fluids by lipoproteins which may be classified according to their density, for example, the very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL), low density lipoproteins (LDL) and high density lipoproteins (HDL).

It has been shown that high levels of LDL-cholesterol in the blood correlate with atherosclerosis which is a progressive disease characterized in part by sedimentation of lipids in inner walls of arteries, particularly of coronary arteries. It has also been shown that a high blood level of LDL- cholesterol correlates with coronary heart disease. Also, a negative correlation exists between blood levels of HDL cholesterol and coronary heart disease.

The level of total cholesterol in blood, which is the sum of HDL-cholesterol, LDL-cholesterol, VLDL-cholesterol and chylomicron-cholesterol, is not necessarily predictive of the risk of coronary heart disease and atherosclerosis.

The correlation between atherosclerosis and LDL cholesterol levels, however, is much higher than a similar correlation between atherosclerosis and total serum cholesterol levels.

In some embodiments, the compounds as herein described and/or compositions comprising the same may be used for applications in, or treating diseases or conditions associated with a subject having diabetes. In one embodiment, the subject for whom treatment is sought via the methods of this invention is one with diabetic I. Type I diabetes is characterized by autoimmune destruction of pancreatic beta-cells. Markers of immune destruction of the beta-cell are present at the time of diagnosis in 90% of individuals and include antibodies to the islet cell (ICAs), to glutamic acid decarboxylase (GAD), and to insulin (IAAs). While this form of diabetes usually occurs in children and adolescents, it can occur at any age. Younger individuals typically have a rapid rate of beta-cell destruction and present with ketoacidosis, while adults often maintain sufficient insulin secretion to prevent ketoacidosis for many years. Eventually, all type I diabetic patients require insulin therapy to maintain normoglycemia.

In one embodiment, this invention provides a method of treating diabetes type II. Type II diabetes is characterized by insulin resistance and at some stage in pathogenesis of the disease, a relative deficiency of insulin secretion. In absolute terms, the plasma insulin concentration (both fasting and meal- stimulated) usually is increased, although “relative” to the severity of insulin resistance, the plasma insulin concentration is insufficient to maintain normal glucose homeostasis. With time, however, there is progressive beta cell failure and absolute insulin deficiency ensues. Most individuals with type II diabetes exhibit intra abdominal (visceral) obesity, fatty liver, which is closely related to the presence of insulin resistance. The patient's liver becomes insulin resistant and glycogen breakdown is uncontrolled and the result is increased and unphysiological glucose delivery to the bloodstream. The liver generated cholesterol and VLDL particles is also uncontrolled. In addition, hypertension, dyslipidemia (high triglyceride and low HDL-cholesterol levels; postprandial hyperlipemia), and elevated PAI-1 levels often are present in these individuals. This clustering of abnormalities is referred to as the “insulin resistance syndrome”, or the “metabolic syndrome” or obesity related disorders. Because of these abnormalities, patients with type II diabetes are at increased risk of developing macrovascular complications such as myocardial infarction and stroke.

In one embodiment, this invention provides a method of treating diabetic nephropathy. Diabetic nephropathy is a complication of diabetes that evolves early, typically before clinical diagnosis of diabetes is made. The earliest clinical evidence of nephropathy is the appearance of low but abnormal levels (>30 mg/day or 20 μg/min) of albumin in the urine (microalbuminuria), followed by albuminuria (>300 mg/24 h or 200 μg/min) that develops over a period of 10-15 years. In patients with type 1 diabetes, diabetic hypertension typically becomes manifest early on, by the time that patients develop microalbuminuria. Once overt nephropathy occurs, the glomerular filtration rate (GFR) falls over a course of times, which may be several years, resulting in end stage renal disease (ESRD) in diabetic individuals.

In one embodiment, this invention provides a method of treating diabetic neuropathy. Diabetic neuropathy is a family of nerve disorders caused by diabetes. Diabetic neuropathies cause numbness and sometimes pain and weakness in the hands, arms, feet, and legs. Neurologic problems in diabetes may occur in every organ system, including the digestive tract, heart, and genitalia. Diabetic neuropathies are classified as peripheral, autonomic, proximal, and focal. Peripheral neuropathy causes pain or loss of feeling in the toes, feet, legs, hands, and arms. Autonomic neuropathy causes changes in digestion, bowel and bladder function, sexual response, and perspiration and can also affect the nerves that serve the heart and control blood pressure. Proximal neuropathy causes pain in the thighs, hips, or buttocks and leads to weakness in the legs. Focal neuropathy results in the sudden weakness of one nerve, or a group of nerves, causing muscle weakness or pain. Any nerve in the body may be affected.

In one embodiment, this invention provides a method of treating diabetic retinopathy. The effect of diabetes on the eye is called diabetic retinopathy. Patients with diabetes are more likely to develop eye problems such as cataracts and glaucoma. The affect of diabetic retinopathy on vision varies widely, depending on the stage of the disease. Some common symptoms of diabetic retinopathy are blurred vision (this is often linked to blood sugar levels), floaters and flashes and sudden loss of vision.

In one embodiment, the subject for whom treatment is sought via the methods of this invention is one with glucose intolerance. Glucose intolerance is a pre-diabetic state in which the blood glucose is higher than normal but not high enough to warrant the diagnosis of diabetes.

In one embodiment, the subject for whom treatment is sought via the methods of this invention is one with hyperinsulinemia. Hyperinsulinemia is a sign of an underlying problem that is causing the pancreas to secrete excessive amounts of insulin. The most common cause of hyperinsulinemia is insulin resistance, a condition in which your body is resistant to the effects of insulin and the pancreas tries to compensate by making more insulin. hyperinsulinemia is associated with type II diabetes

In one embodiment, the subject for whom treatment is sought via the methods of this invention is one with insulin resistance. Insulin resistance is a condition in which normal amounts of insulin are inadequate to produce a normal insulin response from fat, muscle and liver cells. Insulin resistance in fat cells results in hydrolysis of stored triglycerides, which elevates free fatty acids in the blood plasma. Insulin resistance in muscle reduces glucose uptake whereas insulin resistance in liver reduces glucose storage, with both effects serving to elevate blood glucose. High plasma levels of insulin and glucose due to insulin resistance often leads to the metabolic syndrome and type II diabetes.

Diabetes and the liver obesity is typically associated with elevated levels of free fatty acid (FFAs) that promote lipid accumulation and insulin resistance in target tissues, i.e. reduced action of insulin primarily in skeletal muscle and liver. A prominent role of insulin is to reduce glucose output from the liver. FFAs stimulate hepatic gluconeogenesis which per se does not lead to increased hepatic glucose output as long as it is paralleled by a decrease in hepatic glycogenolysis, a compensatory process referred to as “hepatic autoregulation”. FFAs stimulate insulin secretion and insulin blocks glycogenolysis in part by inhibiting secretion of glucagon, an inducer of glycogenolysis. However, long-term elevated levels of FFAs leads to hepatic insulin resistance and thus breakdown of hepatic autoregulation, resulting in increased hepatic glucose production and development of type II diabetes. Fatty liver and hepatic insulin resistance is a major driving force behind hyperglycemia and type II diabetes.

In one embodiment, this invention provides methods that inhibit (improve) the fatty liver, resulting in that the insulin resistance in the liver is inhibited (improved) and thereby solving the basic problem in type II diabetes.

In another embodiment, the diabetes is a type I diabetes. In another embodiment, the diabetes is a type II diabetes.
